Patented Jan. 27, 1931 UNITED STATES PATENT OFFICE PAUL KOHLOFF, OF HAMARONECK, NEW YORK, ASSIGNOR F ONE-HALF TO GEORGE GROSS, OF SUMMIT, NEW JERSEY ELECTRICAL CONNECTER.

Application filed December 15, 1928. Serial No. 326,205.

This invention relates generally to spark plug and coil or distributor connecters and has more particular reference to a novel electrical connecter, one form of which I disclosed in my previous Patent No. 1,566,143,

dated. December 15, 1925.

The invention has for an object the provision of a device of the class mentioned, which is of simple durable construction, desirable 0 in use and efficient in action, and which can be manufactured and sold ata reasonable cost.

The invention proposes the use of a metal springy strip provided with an aperture at one end for engaging upon a terminal and a cut-out portion at the other end forming a jaw for engaging upon a second terminal. The strip is adapted to be bowed when engaged between the terminals so that a con stant force is exerted by the strip for maintaining its position. Preferably, an eyelet is engaged in the aperture in the said springy strip. The coating of insulating material may be applied upon the strip. This strip may be modified in various ways such as engaging eyelets in both ends of the strip, and forming cut-out portions in both ends of the strip for providing jaws. A further modification consists of cut-out portions formed in the eyelets arranged for aligning with the cut-out portions of the strip in certain positions of the eyelets, the eyelets being arranged to rotate to different positions. This arrangement permits the connecter strip to be locked upon a terminal.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and

to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a perspective view of a strip constructed according to this invention and applied upon terminals.

Fig. 2 is a fragmentary plan view looking in the direction of the arrows 22. of Fig. 1.-

Fig. 3 is a fragmentary sectional View, taken on the line 33 of Fig. 2.

Fig. 4 is a plan view of the strip per se.

Fig. 5 is a fragmentary side elevational view thereof.

Fig. 6 is a sectional view of a modified form of a strip seen as though taken 011 the line 6-6 of Fig. 4.

Fig. 7 is a View similar to Fig. 4, but disclosing a modified form of the device.

Figs. 8 and 9 are further similar views to Fig. 4, but disclosing further modified forms of the device.

Fig. 10 is a view similar to Fig. 5, but disclosing a modified form thereof.

Fig. '11 is another similar viewto Fig. 4 disclosing a further modified form of the device.

Fig. 12 is a sectional View, taken on the line 1212 of Fig. 11.

. Fig. 13 is a fragmentary view of a portion of Fig. 11 showing the eyelets thereof in a second position.

Figs. 14 and 15 are views similar to Fig. 11, but disclosing modified forms thereof.

Fig. 16 is a plan view of a flexible cable with end clips constructed according to this invention.

Fig. 17 is a similar View to Fig. 1 showing another application of my connecter.

The reference numeral 20 indicates generally a. coil box provided with binding posts 21 having binding nuts 22 on their ends. The reference numeral 23 indicates generally a spark plug having a binding post 24 and .a binding nut 25. An electrical connecter 26 constructed according to-this invention is shown engaged between a binding post 21 and the spark plug 23.

The conneeter 26 comprises a metallic springy strip 27 having an enlargedrend 28 with an aperture 29 in which an eyelet 30 is en aged. The other end of the strip 27 also as an enlarged portion 31 formed with a cut-out 32 to provide a jaw 33. As shown in Fig. 1, the eyelet 30 is engaged upon one of the binding posts 21,- and the jaw 33 is engaged upon the spark plug 23. The binding nut25-ofthe spark plug is formed with flattened sides 34 for receiving the jaw 33 as clearly shown in Fig. 3. If desired, the jaw 33 may be clamped between the binding nut 25 and the spark plug as indicated by dot dash lines 35.

In the modified form of the device illustrated in Fig. 6, an opening 29' formed in one end of the connecter 26 has integral turned ends as indicated by numeral 36. This serves as an eyelet for reinforcing the opening 29'.

In the modified form of the device 'illustrated in Fig. 7, an electrical connecter 26 has been illustrated of the same width along its entire length. The cut-out 32 communicates with a circular cut-out portion 32*. In other respects this connecter is similar to the preferred form of the device.

In Fig. 8 the connecter 26 is illustrated with cut-out portions 32 at both ends forming jaws 33. The eyelet 30 is shown engaged in one of these jaws so that the strip may function as before described relative to Fig. 4. a

In Fig. 9 a second eyelet 3O has been shown engaged in the end of the strip opposite to that provided with the eyelet 30. '1 his connecter is engaged upon the terminals with the binding posts engaged thru the eyelets.

Fig. 10 shows another modified form of the device in which reinforcement washers 37 are engaged on both sides of the connecter 26 at the portions thru which the eyelets 30 engage. Thus the connecter is materially strengthened where it needs most strength.

In Figs. 11, 12 and 13 a connecter 26 has been illustrated with cut-outs 38 extending into the strip 27 and the eyelet 30. The eyelet is rotatively mounted on the strip 27 so that it may be rotated to a second position as illustrated in Fig. 13. In this position the cut-out portion of the eyelet does not align with the cut-out portion of the strip and a binding post engaged thru the eyelet is thus locked in position. The advantage of this construction is that the connecter may he slipped upon a binding post having a nut without removing the nut.

In Fig. 14 a connecter 26 has been illustrated formed at both ends with cut-outs 38 and eyelets 30. This arrangement permits both ends of the connecter to engage upon binding posts and to be locked in positions by rotation of the e elets 30.

In the modified form of the device illustrated in Fig. 15, a connecter 26 has been illustrated with cuts 38 in the sides thereof near the ends. Eyelets 3O are rotatively mounted onthe strip and are provided with cuts normally aligned with the cuts in the connecter strip. The operation of this form of the device is similar to that described its ends. The clip 40 is provided with an eyelet 42 so that this end of the cable may be secured upon a binding post. The clip 41 with an eyelet 43 is formed with a cut 44 in the material forming the clip and in the eyelet; Normally these cuts align, and the eyelet is rotatively arranged so that it may be rotated for disaligning the cuts and permitting a binding post engaged thru the eyelet to e locked against displacement.

In Fig. 17 a cut-out end 32 of the connecter 26 is shown to be connected to the binding post 21 of distributor 20 and an enlarged end 28 of connecter 26 is connected to spark plug 23.

It is to be understood that my connecter may be used to connect binding posts of spark plugs, distributors or any electrical terminal or device wherever an electrical connecter, the type above described, may be used.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is An electrical connecter, comprising a single piece of relatively springy metal strip having cut-in ends forming aws, and an eyelet rotatably mounted in one of the jaws, the said eyelet having a cut-out portion aligning with the cut-in in the strip in one position of the eyelet.

In testimony whereof I have aflixed my signature.

PAUL 'KOHLOFF.
